style: unify card styles across calendar, statistics, and budget pages

- 调整 theme.css 中的 --radius-lg 为 12px 以符合设计标准
- 统一日历页面卡片样式（padding, border-radius, shadow）
- 统一统计页面所有卡片组件的样式
- 统一预算页面图表卡片样式，替换硬编码值为 CSS 变量
- 为关键样式添加 fallback 值以防止变量未定义
- 所有卡片现在使用统一的样式变量：
  - padding: var(--spacing-xl, 16px)
  - border-radius: var(--radius-lg, 12px)
  - box-shadow: var(--shadow-sm)
  - background: var(--bg-secondary)
